3-D Video Games

The world of 3-D video games, any gamer will tell you, is almost as old as video games in color: Nintendo titles in the late 1980s like Rad Racer and 3-D WorldRunner each had 3-D modes that used red-and-blue passive eyeglasses to produce images that jumped off the screen just like 1950s-era movie monsters.

What's new in 2010 is the prospect of 3-D games running on the new 3-D television sets coming onto the marketplace. Sony is promoting 3-D video games on its PlayStation 3—firmware upgradable to run on 3-D TVs—such as James Cameron's Avatar and Invincible Tiger: The Legend of Han Tao. On the other hand, some video-game makers are holding back, preferring the old-fashioned method that uses colored glasses, in new titles such as Batman: Arkham Asylum and Skate 2.

Digging Into the New QD-OLED TVs

Formerly rival technologies have come together in Samsung displays

Sony's A95K televisions incorporate Samsung's new QD-OLED display technology.

Televisions and computer monitors with QD-OLED displays are now on store shelves. The image quality is—as expected—impressive, with amazing black levels, wide viewing angles, a broad color gamut, and high brightness. The products include:

All these products use display panels manufactured by Samsung but have their own unique display assembly, operating system, and electronics.

I took apart a 55-inch Samsung S95B to learn just how these new displays are put together (destroying it in the process). I found an extremely thin OLED backplane that generates blue light with an equally thin QD color-converting structure that completes the optical stack. I used a UV light source, a microscope, and a spectrometer to learn a lot about how these displays work.
